1. Ca²⁺ antagonistic action

The taenia coil was excised from male Hartley guinea-pig and mounted in a tissue bath containing Ca²⁺ -free 100 mM KCl LockeRinger solution. A resting tension of 0.5 g was applied to the tissue. The contraction, which was induced by cumulative application of CaCl₂, was measured by the isotonic transducer. The tissue bath solution was maintained at 37° C. and bubbled with a mixture of 95% O₂ -5% CO₂. The test compounds were applied 30 min prior to cumulative application of CaCl₂. The degree of Ca²⁺ antagonistic action was expressed as the pA₂ value. The pA₂ values were calculated from dose-ratios which were obtained as the ratio of the concentrations of CaCl₂ producing a 50% maximal response in the presence and absence of the test compound.

2. Anti-arrhythmic action (aconitine-induced arrhythmias in mice)

Male ddY mice weighing about 30 g were anesthetized with pentobarbital sodium given intraperitoneally. Aconitine (1.32 μg/min) was continuously infused into a tail vein 15 min posterior to pentobarbital sodium administration. The standard limb lead II electrocardiogram was monitored by the cathode ray oscilloscope and the appearance of premature ventricular systoles was observed. The amount of aconitine needed to induce arrhythmias was calculated from the time taken to the onset of the first premature ventricular systoles. The test compounds (100 mg/kg) were orally given 60 min prior to aconitine infusion. Their relative potencies to quinidine were compared by the percent increase of aconitine needed to induce arrhythmias.

For oral administration, the active ingredient and pharmaceutical carrier may, for example, take the form of a granule, pill, tablet, lozenge, elixir, syrup, or other liquid suspension or emulsion, whereas, for parenteral administration, the composition may be in the form of a sterile solution.

The invention also includes a method for the treatment of a subject in need of treating cartino vaso diseases, peripheral circulatory insufficiency and cerebral circulation failure, comprising the step of administering to the said subject a sufficient amount for such purpose of a compound of the invention.

The method of using the compounds of this invention comprises internally or externally administering a compound of this invention, preferably orally or parenterally and preferably admixed with the pharmaceutical carrier, for example, in the form of any of the above compositions, or filled into a capsule, to alleviate conditions to be treated and symptoms thereof in a living animal body. Illustratively, it may be used in an amount of about 1 to about 1000 mg per day (divided into three parts), preferably in 5 to 300 mg per day (divided into three parts) for an oral dose, while parenteral dosages are usually less and ordinarily about one-half of the oral dose. The unit dose is preferably given a suitable number of times daily, typically three times.

The unit dose may vary depending upon the number of times given. Naturally, a suitable clinical dose must be adjusted in accordance with the condition, age, and weight of the patient, and it goes without saying that the enhanced activities of the compounds of the invention, together with their reduced side effects, also make them suitable for wide variations, and this invention therefore should not be limited by the exact ranges stated. The exact dosage, both unit dosage and daily dosage, will of course have to be determined according to established medical principles.

The present invention is further illustrated by the following Examples but it, is to be understood that the present invention is not limited in terms of the specific process conditions.

REFERENCE 3-Cyano-3-isopropyl-3-(3,4,5-trimethoxyphenyl)propionaldehyde

To a suspension of 4.68 g of sodium amide in 150 ml of dry tetrahydrofuran were added 15.00 g of alpha-isopropyl-3,4,5-trimethoxyphenylacetonitrile with stirring and under cooling and then 11.94 g of chloroacetaldehyde diethyl acetal at room temperature, and the mixture was refluxed for 1.5 hours. After cooling, 40 ml of water was added to the mixture and solvent was evaporated. The residue was dissolved in ether and the solution was washed with water. The ether layer was dried and evaporated to give 21.99 g of alpha-isopropyl-alpha-(beta-diethoxyethyl)-3,4,5-trimethoxyphenylacetonitrile as a colorless oil.

Mass Spectrum m/z: 365 (M⁺).

A solution of 21.99 g of alpha-isopropyl-alpha-(beta-diethoxyethyl)-3,4,5-trimethoxyphenylacetonitrile in 130 ml of acetone and 66 ml of 10% aqueous oxalic acid was refluxed for 2 hours. After cooling, the solution was adjusted to pH 6 with saturated potassium carbonate solution. The precipitate was filtered off and the filtrate was evaporated. The residue was dissolved in ether and the solution was washed with water. The ether layer was dried and evaporated to give 17.53 g of the desired compound, which was distillated as a pale yellow oil, b.p. 170°-172° C. ( 6 mm Hg).

A solution of 8.09 g of 4-cyano-4-isopropyl-4-(3,4,5-trimethoxyphenyl)butyraldehyde and 4.96 g of 3-(2-nitrophenoxy)-propylamine in 100 ml of methanol was refluxed for 3 hours. After cooling, to the solution was added 0.50 g of sodium borohydride and the solution was stirred overnight at room temperature. The solvent was removed and to the residue was added water. The solution was extracted with chloroform and the extract was washed with water, dried, and evaporated. The residue was chromatographed on silica gel using 10% methanol-chloroform as an eluent to give 6.48 g of the desired compound as a pale yellow oil.

The oxalate of this compound was obtained in the usual manner.

EXAMPLE 11 Alpha-isopropyl-alpha-[3-[N-[3-(2-aminophenoxy)propyl]amino]-propyl]-3,4,5-trimethoxyphenylacetonitrile

4.78 g of alpha-isopropyl-alpha-[3-[N-[3-(2-nitrophenoxy)propyl]amino]propyl]-3,4,5-trimethoxyphenyl-acetonitrile was hydrogenated in 100 ml of methanol over 50 mg of platinum oxide at atmospheric pressure and room temperature. The catalyst was filtered off and filtrate was evaporated to give 4.36 g of desired compound as a pale yellow oil.

The oxalate of this compound was obtained in the usual manner.

EXAMPLE 12 Alpha-isopropyl-alpha-[3-[N-[3-(2-nitrophenoxy)propyl]-N-methylamino]propyl]-3,4,5-trimethoxyphenylacetonitrile

A mixture of 2.58 g of alpha-isopropyl-alpha-[3-[N-[3-(2-nitrophenoxy)propyl]amino]propyl]-3,4,5-trimethoxyphenylacetonitrile, 4.35 ml of 37% of formalin, and 4.35 ml of 90% formic acid was stirred for 1 hour at 90° C. After cooling, to the mixture were added water and potassium carbonate to make it alkaline. The solution was extracted with chloroform and the extract was washed with water, dried, and evaporated. The residue was chromatographed on silica gel using 1% methanol-chloroform as an eluent to give 1.43 g of the desired compound as a yellow oil.

EXAMPLE 13 Alpha-isopropyl-alpha-[3-[N-[3-(3-hydroxymethylphenoxy)propyl]-N-methylamino]propyl]-3,4,5-trimethoxyphenylacetonitrile

A solution of 2.80 g of alpha-isopropyl-alpha-[3-[N-[3-(3-hydroxymethylphenoxy)propyl]amino]propyl]-3,4,5-trimethoxyphenyl acetonitrile and 4.84 g of 37% formalin in 70 ml of methanol was refluxed for 1 hour. After cooling, to the solution was added 2.25 g of sodium borohydride and the solution was stirred for 1 hour at room temperature. The solvent was removed and to the residue was added water. The solution was extracted with chloroform and the extract was washed with water, dried, and evaporated. The residue was chromatographed on silica gel using 10% methanol-chloroform as an eluent to give 0.74 g of the desired compound as a yellow oil.

EXAMPLE 14 Alpha-isopropyl-alpha-[3-[N-[3-(2-aminophenoxy)propyl]-N-methylamino]propyl]-3,4,5-trimethoxyphenylacetonitrile

0.92 g of alpha-isopropyl-alpha-[3-[N-[3-(2-nitrophenoxy)propyl]-N-methylamino]propyl]-3,4,5-trimethoxyphenylacetonitrile was hydrogenated in 20 ml of methanol over 10 mg of platinum oxide at atmospheric pressure and room temperature. The catalyst was filtered off and filtrate was evaporated to give 0.91 g of the desired compound as a yellow oil. The oxalate of this compound was obtained in the usual manner.

The compounds obtained in Examples 15-185 were prepared in the same manner as described in Examples 1-14.
